Description

Technical Field

[0001] This utility model relates to the field of seamless paper tube coating technology, and in particular to a compression-resistant seamless paper tube coating device. Background Technology

[0002] In many industries such as packaging, textiles, and papermaking, seamless paper tubes serve as an important packaging and support material, making the wrapping process crucial. As market demand for seamless paper tubes becomes increasingly diversified, the performance requirements for wrapping equipment are also constantly rising. Developing an efficient, precise, and compression-resistant seamless paper tube wrapping system capable of adapting to the production of paper tubes of different specifications has become a key technical challenge urgently needing to be addressed in the industry.

[0003] In existing technologies, seamless paper tube coating equipment mainly uses a fixed-structure coating head, which uses a mechanical transmission device to wind the coating material onto the surface of the paper tube according to certain process requirements. Its technical principle is usually based on a motor driving a transmission chain or belt, so that the paper tube rotates at a constant speed on a fixed coating mold, while the coating material is fed out from a specific unwinding device, and the coating operation is completed during the rotation of the paper tube.

[0004] However, existing technology has a significant problem: the diameter of the coating head cannot be adjusted. This means the equipment can only adapt to coated rolls of a fixed diameter. In actual production, it becomes difficult to handle paper tubes of different diameters that need to be coated. To produce seamless paper tubes of various specifications, companies often need to purchase multiple coating machines of different specifications. This not only increases production costs but also occupies a large amount of production space, greatly limiting production efficiency and the company's ability to respond to diverse market demands. Therefore, a compression-resistant seamless paper tube coating machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-extrusion seamless paper tube coating device, which aims to improve the problem in the prior art that the coating head diameter cannot be adjusted, resulting in only being able to adapt to coating rolls of fixed diameter and being unable to flexibly meet the production needs of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-compression seamless paper tube wrapping device includes a base, a diagonal brace plate fixedly connected to the side wall of the base, a first motor fixedly connected to the top of the diagonal brace plate, a threaded rod fixedly connected to the output end of the first motor, a limit post fixedly connected inside the base, a support plate slidably connected to the outer wall of the limit post, a second motor fixedly connected to the side wall of the support plate, a rotating wheel fixedly connected to the output end of the second motor, a rotating ring provided on the outer wall of the rotating wheel, and a support assembly provided on the side wall of the rotating ring.

[0008] The support assembly includes a first connecting plate, the side wall of the first connecting plate is fixedly connected to the side wall of the rotating ring, a first gear is rotatably connected to the side wall of the first connecting plate, a semi-circular gear is rotatably connected to the side wall of the first connecting plate, a clamping column is fixedly connected to the side wall of the semi-circular gear, a handle is fixedly connected inside the first gear, a second connecting plate is provided on the side wall of the first gear, and a locking assembly is provided on the second connecting plate.

[0009] As a further description of the above technical solution:

[0010] The locking assembly includes a limiting ring, the side wall of which is fixedly connected to the side wall of the second connecting plate, and a bolt is threaded inside the limiting ring, with one end of the bolt located on the outer wall of the handle.

[0011] As a further description of the above technical solution:

[0012] The base has a support on its side wall, and a slide rail is fixedly connected to the top of the support.

[0013] As a further description of the above technical solution:

[0014] A sliding plate is slidably connected to the outer wall of the slide rail, and the bottom of the sliding plate is slidably connected to the top of the bracket.

[0015] As a further description of the above technical solution:

[0016] A cylinder is fixedly connected to the side wall of the sliding plate, and a moving rod is fixedly connected to the output end of the cylinder.

[0017] As a further description of the above technical solution:

[0018] A rotating plate is slidably connected inside the movable rod, and a support frame is fixedly connected to the top of the rotating plate.

[0019] As a further description of the above technical solution:

[0020] The support frame is rotatably connected to a rotating shaft, and a semicircular plate is fixedly connected to the side wall of the rotating shaft. A connecting component is provided on the side wall of the semicircular plate.

[0021] As a further description of the above technical solution:

[0022] The connecting assembly includes a semi-circular bearing, the sidewall of which is fixedly connected to the sidewall of the semi-circular plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, rotating the handle drives the first gear to rotate, the first gear rotates and drives the semi-circular gear meshing with it to rotate, the semi-circular gear drives the clamping column to converge, thus achieving the effect of adjusting the diameter of the coating head. This solves the problem that the diameter of the coating head cannot be adjusted, which leads to the inability to adapt to film rolls with a fixed diameter and to flexibly meet the production needs of different specifications, thereby improving the versatility of the anti-extrusion seamless paper tube coating equipment.

[0025] 2. In this utility model, the moving rod is driven by a cylinder to move, the moving rod drives the rotating plate to rotate, the rotating plate drives the support frame and the rotating shaft to move, and then drives the semi-circular plate and the semi-circular bearing to fit together, which achieves the effect of auxiliary support for the paper tube. This solves the problem that when there is a lack of support, the covering pressure causes the paper tube to become elliptical or concave, affecting the roundness of the finished product, and improves the stability of the anti-extrusion seamless paper tube covering equipment.
